35weeks Pregnant. I live in Washington State. I'm at the point in my pregnancy where almost everything is a struggle & my hips and back are in constant pain. Due to a family emergency me and my fiancé are planning on driving to California this weekend, I'm super nervous to travel while being so close to my due date... Any other ladies had this issue? What was your experience any advice ?
